Veteran creatures.

Elves, elves, and more elves. They are in all parts of the game, everywhere at the early levels, and always very strong! Because they are elves, probably.

Now we're focusing on wolves))) I don't remember if they were in the first part, but they were definitely in all the others)) although I don't think they were in the third one

Yes, in the first part, they are a second-level unit for the Barbarians. A powerful unit!
